Demicellization of Polyethylene Oxide in Water Solution under Static Magnetic Field Exposure Studied by FTIR Spectroscopy

Figure 2

Representative spectra in the region 1500–1000 cm⁻¹ of PEO in water solution after 2 h (a) and 4 h (b) of exposure to a SMF at 200 mT. The strong vibration band around 1465 cm⁻¹ is splitted in two bands and can be assigned to CH₂ scissoring vibration bands. The 1349 cm⁻¹ peak is related to the EO methylene wagging vibrations of the gauche conformation. The strong band around 1080 cm⁻¹ can be assigned to the C–O–C stretching hydrated bond. Red and blue lines refer to exposed and unexposed samples, respectively.
